DDMSence is a Java API that supports the DoD Discovery Metadata
Specification (DDMS) and can transform XML DDMS Resource records
into a Java object model. It can also perform logical validation of
rules that are not coded into the DDMS schema.

With this release, the bundled schema files have been updated to
support DDMS 3.0 and an online DDMS validator has been added to the
project homepage.
